phi · Answer

density it mass per volume  or
mass/volume

if you multiply mass/volume times volume  you will get mass  (notice that volume divided by volume becomes 1)

so multiply mass/volume (otherwise known as density) times volume 
to get the mass

volume is 1592 cubic meters
density is 0.1785 kg / cubic meter

mass is volume * density

when you do the multiplication, the two cubic meters units cancel out, leaving you with only kg as the unit.
